What is EN ISO 12405-2:2018?

EN ISO 12405-2:2018 is a technical standard that specifies the testing requirements for electrically propelled road vehicles in order to evaluate their safety performance. This standard focuses on the electrical performance of the vehicle's propulsion system, including the high-voltage energy storage systems and the electrical safety of the vehicle as a whole.

Scope of EN ISO 12405-2:2018

The scope of EN ISO 12405-2:2018 covers various aspects related to electrical safety performance testing of electrically propelled road vehicles. It includes requirements for the test procedures, test conditions, and test methods to be followed during the evaluation process.

This standard applies to electric vehicles (EVs), which are exclusively propelled by electricity, and hybrid electric vehicles (HEVs), which combine both rechargeable energy storage systems and an internal combustion engine.

Key Components of the Standard

EN ISO 12405-2:2018 specifies the following key components:

High-voltage measurement equipment requirements: The standard outlines the necessary characteristics, calibration procedures, and uncertainties for the measurement equipment used in the evaluation of electric vehicle safety performance.

General test conditions: It provides guidance on the ambient conditions, as well as specific test chamber requirements, for conducting the safety tests on electric vehicles.

Electrical safety test procedures: The standard defines various tests to assess the electrical safety performance of the vehicle. These include tests for insulation resistance, electrical continuity, fault protection, and dielectric strength, among others.

Benefits of EN ISO 12405-2:2018

Adhering to the guidelines set forth in EN ISO 12405-2:2018 offers several benefits to manufacturers and consumers of electric vehicles alike:

Ensures safety: Compliance with this standard guarantees that electric vehicles meet stringent safety requirements, mitigating the risks associated with electrical faults and hazards.

Promotes interoperability: By establishing uniform test procedures, it facilitates the comparison of different electric vehicle models and simplifies cross-compatibility between charging infrastructure and vehicles.

Boosts consumer confidence: The adherence to safety standards enhances consumer trust in electric vehicles, thereby promoting their adoption and market growth.
